Château de Franchimont

Château de Franchimont is a medieval fortress located in the municipality of Theux within Liège Province, Wallonia, Belgium. Situated on a small hill approximately two kilometers south of the village, the castle originally dates back to the 11th century when it served as a strategic stronghold for the Prince-Bishopric of Liège. Over the centuries, the structure underwent several expansions, particularly after suffering fire damage in 1387. By the late 15th century, the La Marck family assumed ownership, and significant military upgrades were implemented in the early 16th century. These additions included a robust outer wall, casemates, and a dedicated artillery tower, reflecting the evolving nature of warfare during that era.

Historically, the site held considerable political importance as the base of the Marquessate of Franchimont, a small province governed by the prince-bishops who adopted the title of Marquis of Franchimont. This territory was bounded by the Duchy of Limburg, the Duchy of Luxemburg, and the Princely Abbey of Stavelot-Malmedy. Although the castle has seen periods of conflict, including a notable siege in 1487, it remains a defining landmark of the region. Today, the property is owned by the town of Theux and operates as a public attraction. While parts of the structure are in ruins, including the remains of the keep, the north-east artillery tower has been repurposed to house a small exhibition and the ticket office, allowing visitors to explore its rich past.
